If the suggested solution in that thread doesn't work, there are somequestions:

1. What does your setup look like, are you running HBase in standalone modeor is it distributed?2. Is the HBase master web UI accessible, the default port is 60010, if thepage is up what do you see?3. Have you enabled any security settings for zookeeper or is this a stockinstallation? (based on the logs you pasted you are able to createconnections and communicate with zookeeper so it might not be securityrelated)

Also, can you post logs from the master from during start up, preferablywithout the zookeeper debug logging. I've found the zookeeper logs to bequite chatty. Logs will make it a lot clearer where the master is gettinghung up.
